Can you post the error message / stack trace?
Overlapping pokes probably means two threads tried to poke the same line
from chiseltest.

Sure. If I only keep the B part and comment out A and C like this
// ... Line 36
fork{
d.io.enq1.enqueueSeq(Seq(10.U, 11.U, 12.U))
}.fork{
// --- A ---
// d.clock.step(10)
// d.io.deq1.expectDequeueSeq(Seq(10.U, 11.U, 12.U)) // This works fine, of course.
// --- B ---
// What should I do if I have to avoid using `expectXXX()` methods? ( since I cannot know the exact output in some complex modules other than Queue )
// This will give me a timeout error. `deq1.ready` keeps false in waveform.
d.clock.step(10)
d.io.deq1.ready.poke(true.B)
// --- C ---
// This pokes `deq1.ready` for only 1 cycle
// d.clock.step(10)
// fork{
// d.io.deq1.ready.poke(true.B)
// d.clock.step(1)
// }.join
}.join
// Line 54 ...Then I get:
timeout on dualQueue.clock: IO[Clock] at 1000 idle cycles. You can extend the timeout by calling .setTimeout(<n>) on your clock (setting it to 0 means 'no timeout').
chiseltest.TimeoutException: timeout on dualQueue.clock: IO[Clock] at 1000 idle cycles. You can extend the timeout by calling .setTimeout(<n>) on your clock (setting it to 0 means 'no timeout').

And io.deq1.ready keeps 0 in the vcd waveform. Am I missing something important about fork usage?
